LUBmeaToR.

To all wh'om it may concern:

Be it known that I, O'r'ro IjIAJnK, a subject ofthe 'Emperor ofAustria-Hungary, residing at Vienna, Austi'ia-IIuiigary, have in- 5vented certain new and useful Improvements in Lubricatois, of which thefollowingis a specification. Y

The presentzinvention relates to a lubricator havinga plurality ofpumpsadapted L0 to be connected to a common oil reservoir Y K4and embodying asight glass which is 4filled `enthe1eservoir to'normally indicate 'thelevel of oil therein 11iconpinetion with means whereby communication maybe esone of said pumps in order to indicate the rate of feed thereof.

The essential feature ofthe invention involves the provision of meanswhereby each separate pump can .be broughtinto communicationwith a sightglass which is at the seine time eut off from the'oil reservoir, so thatthe oil in the sight glass flows to the pump which is connected to thesight glass.

During such connection between the sight glass andpump, the oil in thesight glass will sink-or fall at a ate ydepending upon the amount ofloil discharged by the particular pump connected to the sight glass,

thereby affording .means for indicating whether the particular pumpconnected with the sightk glass is 4in proper` working condition and therate of feed of such pump.

lIn the accompanying drawing: Figure Vl represents a vertical sectionthrough one form of lubricator wherein two -oilpumps are arranged in theoil reservoir;l Figs.`2

and 3 represent horizontal cross sectionsl through the lower portion ofthe lubricator and show the action of the controlling valve in thedifferent positions which it is adapted to occupy.'

The pump pistons p and p may be ae tuated 1n any' suitable way, aneccentric Z) p15 being provided for that purpose in the present instancehaving a twoarnied sleeve a.-

being arranged preferably upon the same level `as the oil reservoir inorder that the height of the column of oil in the sight glass maynormally indicate the level of oil within therese voir.

All o f tlieducts leading from the oil res-- ervoir to the pumps and tothe sight glass pass through a controlling valve li. .which inthepiesent instance is in the form of a conical cock. However, theinvention is not limited to a controlling valve of the specific formshown as an equivalent device may be employed. lt will also be understood that the invention is not limited to the use of pumps of thespecific form shown,v

The controlling valve /1I is providedfeyithg a duet :1; whichaceordiiigto its positiii,v which may be changed by the handle. y, iscapable of bringing` the channel or pipe c and consequently the sightglass, into co`n` nection either with vthe oil reservoirI as shown inFig. 3 orwith one Apump cylinder through the oil feed ducts as shown inFigs. l and 2. li`urtherinore, a channel y is formed in t-liecontrolling valve which is connected by the branch y with the-oilreservoirl through the opening 0. This channel fz/ is eap'able'ofconnecting the oil reservoir with the cylinder of eitlieir.1' iiijnp. Ifthe controlling valve 7L is so rotated that itfassumes the positionshow-n in Figs. and 2, the piston cylinder Z is'eonn'ectedl with the oilsight lglass s through the chan'- nels 63a' and the channel or pipe -e`while at the saine time the cylinder d and the oil sight glassI have nocommunication-wi-th t-he l l yoil reservoir or the' channelv oleadingthcieto. rlhe cylinderd-I Iofthe other punipis in thisposition,connected-:to the oil reser-l 'voir through-thechannelscf5phy', and of'.

'l`herefore, with the parts occupying the po-j sition shown in Figs. 1and 2, the pump' p 'receives its oil solely from the sight glass s,

At thesame time boththrough the channels y and y and, there fore, bothpumps receive oil directlyV from the oil reservoir, and upon the descentof I ythe pistons the oil contained in that part of the cylinders Z andd below the chan' nels o and o will be compressed and forced throughsuitable valves to the mechanism to be lubricated.

Under normal conditions, the oil pumps in the oil reservoir both receiveoil from the oil reservoir While the glass s acts .only as a sightglass.

from the oil reservoir and is connected with the. particular pump undertest, The

Iheight of thevcolumnof oil in the sight glass will fall according tothe rate of feed of the particular pump to which the sight glass is thenconnected. Normally, however, as

stated, the, pumps receive oil directly from Athe common reservoirthrough the passages a and c', th'semi-cireular channel y in the portedvalve, the passage jz/l in the valve andthe passage 'of communicatingwith the reservoir, the sight' glass .s at this time bel ing incommunication with. the reservoir through the pipeorpas'sage e, thecentral port a: of the valve and the passage or channel o leading fromthe reservoir, and when the sight glass is so connected, it serves as anindicator to show the amount of oil contained in the reservoir.

Claim:

l. In a lubricator, the combination of an oil reservoir, a pump'having achannel leading thereto, a sight tube .disposed on appro'ximately thelevel of the reservoir and having a channel communicating therewith, anda valve having a duct for establishing communication between the sighttube and the reservoir to charge'the said tube with oil when thevalveoccupies one position and for establishing communication between thesight tube and the pump when the valve oc- When, however, it isdesirable to determine whether and to what devreservoir and having meansfor establish* ingcommunication therewith, and a valve ycapable of'being set in one position to establish communication between the reser-'voir and the sight tube and capable of being set in a differentposition to establish communication between the sight tube and thepump'.

3. In a lubricator, the combination of an oil reservoir, a pump, a sighttube capable of receiving a charge of oil from the reser voir, and adevice capable of being set in one position'to establish communicationbetween the reservoir and both the pump and the sight tube and capableofbeing set in a different position to establish communication between thesight tube and the pump.

l. In a lubricator, the combination of an oil reservoir, a lurality ofpumps, a sight tube capable o receiving a charge of oil from thereservoir, and a device capable of being set in one position toestablish coinmunication between the sight tube and ono of said pumps'and between the said reservoir and another of said pumps. y

5. In a lubricatonthe combination of au oil reservoir, al' lurality ofpumps, a sight tube capable ofp receiving a charge of oil from thereservoir, and a device capable of' being set in one position toestablish 'coinmunicationbetween said sight -`tube and either one ofsaid pumps and maintaining communication between the reservoir and.4

anothenof said pumps` and capable of4 oefl cupyingV a different positionto establish.

'communication between the reservoir and the pumps and lbetween thereservoir and the sight tube.

In testimony whereof I have'hereunto set my hand `in presence of twosubscribing witnesses.
